Pratt and Whitney R-4360 - Run October 2, 2008 Penngrove, CA

[Desmodromic916]

This engine starter has more kw than then my VW

[airportknpi]

This would have been so much cooler in HD with stereo sound.

[irish89055]

nice... but still not the stereo sound I want.. the only one on here so far has gratuititous background music..... huh sgt?

[rEdf196]

put that thing in a slingshot dragster

[TurboRobere]

@Aerozine50 Great info ! It's really cool to think about the firing order of a 28 cyclinder radial engine!! Thanks for sharing. I love internal combution engines. Two stokes, four stokes, Motorcycles, Cars, Planes & Ships, 50cc-21,000rpm, 6cyl 24 valve motorcycle engines, V-12 automobile engines(I've always loved since a kid), 3 story tall container ship engines & Especially radial engines !!

[TurboRobere]

VERY COOL ! My girlfriend & I saw that engine in a floor level glass display case under the left wing of "The Spuce Goose" back in the early 1980's next to The Queen Mary steamliner in Long Beach, Ca. We were lucky to get the tour inside including the huge cockpit. There were actually a couple of big DESKS for free standing insturment boxes behind the pilots seats! Haa. There were benches on ea' side of the engines inside of ea' engine comartment to work on them while IN FLIGHT ! Amazing plane!

[Gen96Phx]

I might have to download this for my lullaby! Such a beautiful sound! Thank you for your work and thanks to all who have served this great country.

[aussiecat08]

@jacklav1

They do it like that for cooling , it is an air-cooled engine, all the cylinders have cooling fins on the barrels. Hence the cylinders are aligned so that they all receive cooling airflow.

[jacklav1]

Why are the cylinder locations twisted from one bank to the next, why not twist the crankshaft phasing instead and have them all in line? Surely it would have been cheaper to make like that. There must be a good reason...

[Rob187ok]

Mechanics must have a job on when one of these came in for a overhaul

[TheAmericanRifleman]

That would make a bad as air boat.

[check6ii]

Nice corncob engine. good to see one running again

[j4cko56]

If that was a car engine, i feel miles per gallon would be silly, it would be gallons per mile!!!

[beeroosterm]

@frontenginedragsterd Insane. Absolutely insane. It would be great to get this and other stories together and publish them in some manner (blog, perhaps) to demonstrate to what ends people would go (ordered or not) to protect our country. There's a TV show out there called "Dirty Jobs" - I'll bet they've never heard of something like this!

[beeroosterm]

@frontenginedragsterd Who the hell volunteered for that duty? Great piece of history you've just related here...

[irish89055]

the ultimate recip... though a mechanics nightmare, 56 plugs to change when fouled,

Howard won't miss it...I need for my C-119

[338lapsniper]

Wow this gives me a hard on, now you need to figure out how to put it in a old f4u with a way to small.....high pitch prop.........yessssss, I read that these things burn oil like crazy though 100 gallons of oil and they ran out sometimes on missions, what a monster.

[cylonBS]

The Engine that powered the Goodyear F2G Super Corsair's. What an Incredible Plane .

[Baphamatt]

Wow thx the treat

[andben]

what is the popping sound? is it poor tuning? or lack of any exhaust pipes?

[ilangsfs]

What's the rpm range on one of these?  I know cameras have a hard time picking up rotating things, but it seems really slow.

[stecoop01]

I read somewhere (Great American Aircraft, I think) that with a super charger, these puppies could put out nearly 5,000 horsepower.

Now if I could just figure out how to 'shoe horn' one into a mo-ped frame.

[Beemerboy324]

Love the dog!

[nitroford7900]

The B-29 did not have the 4360 as a powerplant. It had the 3350!

[FiveCentsPlease]

@nitroford7900

Work began to add the 4360 to the B-29 as a B-29D version, but the war ended. The new design became the B-50 after the war.

[N747PA]

Now all you need is five (or seven) more to make some beautiful music......

[kimmer6]

0:37 Boy, Chainsaw is one brave dog! He sure put that old P&W in its place!

[shortribs11]

I have changed many a cylinder on these giants for the AF. Our C-124's carried them proudly and I still get goose bumps thinking of taking all 4 to power. Great job, wish I could be there with you.

[zengsu881004]

OH MY LORD, THIS IS THE REAL AMERICAN MUSCLE !!!

[redcoupe30]

My Father has many hours in KC-97 with four of these engines! Thanks for the vid!

[TownBranchDandy]

99% of B-29's Had Wright 3350 Engine, Some Had 4360's, but only a few test beds.

[FarrarMax]

This was truly a labor of love. I wish my uncle, Carl Kopplin, was alive to see this. He was an engineer and engine designer for P&W all during the 30's, 40's and into the 60's, and used to visit us in Sebastopol whenever he was out on the West Coast.

[foceptik]

F2G . .. .

[JGMagoo]

I have flown in the Flight Engineer's compartmnet on a C-97 which used four of these R4269s. What an incredible experience!

[JGMagoo]

Fantastic job of getting this priceless piece of avaition history running! Thanks so much for your efforts to show the people of future generations what the people of our generation did and sacrificed to protect and preserve their freedom!

[TheKak70]

We had four of these on our KC 97 tankers and refueled B 47 and B 52's . Lots of memories running these on the ground for various ckecks. Full throttle running on the ground made the Aircraft strain against the brakes and the wheel chocks. 3500 horsepower on take off at 2700 RPM

with water injection

[Alex101652]

Is it the sound quality or does this engine sound like ***p or ###t? Did he ever run it at full power?

[916fanatic1]

how much oil does this beast consume when running?

[kingpin1960]

I love it!!!!!

Thanks for posting

[WakeUpDummies]

What a cute prop! LOL

[Polybun]

Poor quality footage due to poor quality camera used.

No tripod.

One fucking star.

[ilangsfs]

@Polybun You are the type of person that just makes me shake my head every time you decide to open your mouth. How 'bout this. I give you "one fucking star." See? Didn't matter. Just like you.

[HuasoPodrido]

back in the late 60's my old control line cox airplane with it's .02 engine was stronger and more powerful then any engine out there to my imagination

[knox1257]

Are there any aircraft powered by this engine that's still flying today?

[alflurin]

If you can find a Boeing KC97, C97, or 377, yes! Or a special P-47 was fitted with one, the XP72! But basically just in a Museum! In the Castle Air Museum, Atwater, California, USA you can find a 367(Freighter), same engine! Never been there but I've searched it on my books and on the internet!

[Turnpike256]

Heard these went into corsairs for awhile after the R2800's but i cant say for sure.

[eze241]

@Turnpike256 you're probably thinking of the goodyear built corsairs, the second version they built, the F2G used an R4360. seattles museum of flight has one of each version on display.

[Treetop64]

Should put that in a Prius... XD

[pablof59]

What was that at the end, an engine break?

Congratulations to the people that restored such a engineering master piece!!

[recipmech]

What memories. I got to work on these big bad boys for four years starting in 1962. They were installed on the C124 GlobeMasters ( Old Shakey ). They had collector exhaust systems ( with exhaust turbos and sounded wonderful. Master rods were A7,B4,C4 and D1. Didn't want to screw that up!...

[stmarsj]

wow that is one huge moma

[Anacinc]

Man that must have been an incredible time in your life!

Too bad that the airliners these days all are powered by jet engines. I remember when I was a young lad I'd use to run out the door whenever I heard a piston engined airliner in the distance hedding my way... those where the days..

[SosiBibuSuka]

So how many cylinders and what is the top rpm on it? Looks like a nice toy!

[Marshall7302]

28 cylinder 56 sparkplugs, 71.5L displacement Horsepower rated between 3000-4300hp

final drive was geared so the prop tips didnt reach supersonic speeds.

[Shalinar45]

Whats with all the snapping, the timing a bit too advanced? WAY cool, though.

[bigtank2185]

angry dog FTW!!!

[Bamchucknorris]

nice fan lol

[sking0369]

What was all the noise at the end, blower and whistle I hear but the other grinding noise?

[GGigabiteM]

Probably a few pistons combusting at the last second.

[mattsta1964]

Hahahaha! Awesome

Love the little dog freaking out

[bugsier5]

rev it!!!!!

LOL

[dwerke]

Give it to me, I`ll put it into a car!

[MrGuvEuroman]

I love that propeller going backwards/stopping still thing it does when they run : D

[Jthumper]

how many cylinder wasp is that?

[rwp16db]

28 cyl. 4 rows of 7

[emtrixdk]

nowonder sprucey didnt leave more than a few meters from ground

[Fullmetal9876]

could of been the fact that it was made of wood the canadian hercules is designed after the spruce goose but is made of lighter tech and pratt & whitney always makes really good engines so who knows

[Squarerig]

If you want we got it in the USA!What an engine!How were the after cylinders cooled?Must have been quite a problem to achieve that.

[JGMagoo]

Note that the cylinders are staggered in a helical pattern, not directly behind one another. This aids in cooling.

[pinwizz69]

As  a frmr. CG radial flghtmech(HU16e) I can hear hes got a couple of cylndrs. missfiring. probibly old or fouled plugs. those things are big and damn expensive, not ta mention a bitch ta change.

[emtrixdk]

is it just me or it seem like its running like shiate still?

[Paiste402]

its just the V-TEC kicking in

[mbunds]

What a thing of beauty! Did you have to tear it down completely to put it in running order?

[klesmer]

I'd love to hear the old girl at full song.

[J2OLDS]

Aren't you afraid of burning a valve with those small diameter exhaust stacks ?

[wilsonces]

Like a symphony. Bello.

[daytenmillion]

The Resorcinol glue used in most later US-made wood aircraft is far superior to the casein resin glue used in earlier US and European aircraft. If kept hangared lasts indefinitely. My 1946 Bellanca Cruisair is still firmly holding together. A couple of loose joints on cabin stringers from moisture and that's all...

...I believe the Hughes H-1 would fly beautifully. Unfortunately Hughes dropped the project before a Type Certificate was issued. It would have be the world's largest Experimental.

[cutter043]

i think what the people who have the spruce goose should do .. is get that thing up and flying... or least fire the orishinal engines up ... im a huge howard hughes fan.. but i also know he was a lil bonkers in his later yrs... we have the technology i bet the goose could still fly ..

[zoidamachine]

That would be fun to see. Unfortunately, all-wood airplanes rely on glued joints, and are kinda tricky to keep together, like the Focke-Wulf Ta 154 Moskitos that started coming apart after about so many flights. They don't age very well, either. That's why there haven't been any DH Mosquitos flying since the '60s. That might also be why HH was so tentative in flying the Spruce Goose; he was probably scared shitless it was going to come apart. I mean, eight 3000 hp 4360's, kinda "glued" together?

[zoidamachine]

"Hey, flight engineer... was that a "creak" we just heard, or a "crack?"

[Truthseekerfinder]

There are currently at least three serviceable, flying DH Mosquitos flying today.

[hammerogod]

OMG!

What a beauty.

Is it from a Convair B-36? or is it an earlier mod from the B-29?

[PenngrovePower]

It is from the Hughes H-4 cache of engines. Been in the can for about 60 years. We restored it and ran it earlier in the year without a test club - Oh my! Did we know what we were doing? Perhaps we did since the engine is in fine shape as you can see.

The engine is an early production model but without a data plate, we can only infer what it is. Probably from around '42 or early '43. Thanks for your insightful comments on the other videos. Enjoy the show.

[ziggassedup]

do that at nite.i bet you could work out the fireing order..lol.

[beeroosterm]

@hammerogod Why don't you restore the other 7, fire them up, and fly that old plane?!!!!

[release19]

that is a gorgeous sight, thanks for sharing

[pudd750]

proven factoid, little black and white dogs hate radials

[dairwin2000]

... the mil test rigs are designed for running at full power with a full sized prop.

[PenngrovePower]

You're right it's an early model. This came from the Spruce Goose cache of engines from when Summa Corp. was going to cut up the plane in the 80's. The data plate is missing and we suspect this may have been one of the engines that "flew" the H-4 since the original contract required that style of engine for the build. The missing data plate is peculiar.

We never run the engine more than a little above idle so this trailer and stand work well. It's a museum display, not a test stand.

[Henry455]

Spruce Goose HK-1 originally powered and flew with 4360-4A engines (3000 H.P.) of which 16 were built, reengined in 1951 with commercial 4360-TSB3G (3500 H.P. wet) , same engined used in the Boeing Model 377, of which 391 built.

[sakoshooter48]

@PenngrovePower Actually, I work for Evergreen International Airlines, owners of the H-4, and all of the P&W R 4360's were returned to the Department of the Navy after the aircraft was put to bed by Congress. The engines that have always adorned the "Goose" are run-outs. Would love to have eight fresh ones and about three miles of unobstructed waterway!!!!!!!

[legebakkenb]

Yes

I have looked at the vids from this amazing mashine. And I think you should explain to us enhousiasts why we can not hear it at more than idle.

[nocrap62]

what a monster...love these old engines

[D342DIESEL]

run that thing at full bore and take the trailer for a spin, also nice m818 5ton truck in the backround at 4:20

[warbirdfotos]

Is this actually "from" the Spruce Goose?

[oisiaa]

No, just the same type of engine.

[vfrbikeboy]

WOW,what a monster you'v got there mister.

can we see MORE.

greetz,jan from holland

[grogadile225]

Loved the dog running and barking, I'd have to walk over, touch and feel, have a quiet moment then have a Bundy..

Don't panic, Don't panic, Mr Mainwaring
